Bengal chief minister Mamata Banerjee's visit to New Delhi caused some uncharitable posters to sprout on the roadside in some places on Wednesday.

The posters have, however, sparked to some confusion about its creators.

A group that calls itself 'Youth For Democracy' seems to have put up the posters to ridicule Mamata, who is in the capital to participate in a meeting of Opposition leaders. One of the posters shows an angry looking cartoon of Mamata holding a picture of a Muslim man. The accompanying text says: 'Welcome to Delhi, where democracy is alive and kicking, Didi!'

But as photographs of the poster got circulated through news websites, a Twitter handle @yfdindia put out a note, saying: 'Today some posters explicitly expressing a political opinion have been put up in Delhi under ‘Youth for Democracy’ banner. We are independent of the organization stated. We neither hold any affiliation to the mentioned organization nor do we endorse those opinions.'

Recently, the Mamata government had declined permission to Yogi Adityanath's helicopter to land in Bengal. The government had also disallowed events by BJP chief Amit Shah.

It is unclear who is behind the posters in Delhi. What is certain, though, is that Mamata's arrival has been noted and has triggered some buzz.

At Jantar Mantar, Mamata was on the dais with senior Opposition leaders took part in a rally organised by the Aam Aadmi Party against the 'dictatorial' attitude of the central government.

Speaking at the rally, CPI leader D. Raja said the Constitution was under attack under Modi and asserted that Parliament has been undermined and bypassed under Modi. 'Can you allow a Germany-like situation where Hitler overpowered Reichstag (German parliament),' he said.

CPM leader Sitaram Yechury alleged that the BJP was pitting brother against brother. 'There is a need to replace this government for a better India. This chowkidar needs to be removed to save the country. The BJP is like the Kaurava Sena but the Pandavas (Opposition) will defeat them and save the country,' he said.

Interestingly, minutes before Mamata arrived, the two Left leaders moved away from the stage. Other senior leaders at the meeting were Samajwadi Party's Ram Gopal Yadav, AAP's Sanjay Singh, Nationalist Congress Party's Sharad Pawar and Sharad Yadav.
